This thing is a real workhorse! It consistently keeps the humidity in our boat at the perfect level and we've been running it constantly for many months. We have it set up to drain into the galley sink and it is a nice size to sit right on the counter. It is solid and heavy. Since it is draining directly into the sink, we don't have to bother with emptying it. It is not excessively noisy, and it is an excellent value. We had gone through three smaller dehumidifiers that did not last before buying this one.

Unit works great in my crawl space to keep the humidity level where needed. I've had the unit for many months now. I did have a technical question on the unit's performance. Alorair suupport staff was incredibly responsive, with clear easy to follow instructions. Based on their support, and the units performance since last year, if I have a need for another dehumidifier, I would buy again.

I needed a dehumidifier because we had mold in our crawlspace and needed to keep the humidity down. This unit is a good balance between affordability and performance. It was easy to install and setup up, it's pretty much plug in and turn on. The only thing you have to decide beforehand is how you want to pump the water out. I chose to use the pump feature, we just drilled a hole in my crawlspace wall and plumbed the line outside to drain. It's not very loud. Our crawlspace is directly below our living room and I can hear it running but its not disruptive when we are chatting or watching TV. Been installed for several months now with no issues. Would definitely recommend this product.

The media could not be loaded. 13 March 2024 Update: ALORAIR sent me an email asking me to do some testing for them. When I went down stairs an hour or two ago to turn the machine off in preparation of getting the starting humidity for the test they asked for, I noticed water pouring out of the casing again, meaning to me that the plastic condenser tank is overflowing into the casing again - meaning the case is (again) full of water (video I attached today - could not add videos from last week due to Amazon one video limit) - as I had described on 9 March (last week). Yes, that is the 120 volts plug where the water is pouring out (it was a live line). I immediately cut off the electricity to the unit before coming upstairs to send them an email asking for a call. I told them in email and on the call that this point I do not feel safe turning this machine back on without draining both the condenser tank and the housing and letting the housing completely dry before attempting any more testing. They are sending me a shipping label to send it back for testing by their engineers. My gut feeling is poor design compounded by poor QC. I will say the company reps are polite. As always, I will let you know what happens. 12 March 2024 Update: ALORAIR replacement pump did not fix the issue. I sent them an email on 12 March stating that after replacing the pump the machine still did not seem to be working properly. I could hear the compressor but could not see any indication water was leaving the machine via the pump. If I manually pushed the button to force it to drain it, it did make the correct sound, but I could not see any water going through the hose. I did not see any error messages. The pump just wasn’t working… 09 March 2024 Update: ALORAIR shipped me a replacement pump a week or two ago, but I did not install it until today. I'll let you know if the problem is fixed in a day or two. Looking at unit with cover off was informative. Short version is (IMHO) ALORAIR needs to warn buyers who buy a model with the pump that if they configure it to use the pump, and the pump fails, IMMEDIATELY disconnect the power and re-configure the unit for gravity drain to avoid someone getting electrocuted or the sensitive electronics from getting damaged by water. Reason why is unit is designed so water from condenser drip-drains straight down into a plastic tank on that side (your right as looking at unit with cover off) of the unit (electronics are on your left as looking at unit). If pump is configured, the pump suction drains that condenser tank. If pump is not configured (you are using the gravity drain instead), a rubber plug is removed so water in the condenser tank leaves the unit through the hole the plug was in and out the hose you attach. IMPORTANT - if NOT using the gravity drain (plug is in) but instead using the pump (gravity plug must be in for pump to work) AND THE PUMP FAILS, then the water in the condenser tank keep rising until it OVERFLOWS the condenser tank -- and then floods the entire floor of the entire unit (literally creating a pond of conductive water mere millimeters from the 120-volts electronics -- if configured for 120 volts), creating the "leaking from the corner" unit many folks are reporting. The danger here is if you accidently unlevel a non-functioning pump equipped water-filled unit (say by trying to pick it up) while it is plugged in, and the volume of water inside rises in a corner faster than the unit's seams drain it, I believe you stand a better than even chance of being electrocuted. IMHO - the unit needs an unexpected ground sensor that cuts the electricity if a unit configured for pump experiences a pump failure in conjunction with water reaching the unit's floor. I'll post videos taken today of my (first) draining the condenser tank by removing the gravity seal (power was disconnected beforehand) and then my accidently draining the floor of the rest of the unit when I tried to move it and getting deluged by the volume of water sitting on the floor (video shows water overwhelming the 120 volts plug area). Finally, performing the pump replacement procedure per the video I was referred to, it seems to me the QC issues I had opined about before opening the case were proved correct. One water pump clamp was missing (never installed) and the water pickup hose from condenser tank to pump intake practically fell out when I followed the instructions. I suspect that this loosely mounted hose may be the primary source of water exfiltration from tank to floor of entire unit (and possible corrosion issues for electronic components millimeters above a pool of water down the road). Best recommendation I can make at this point is do not attempt to use the pump and configure pump-equipped units to run only in gravity mode. If you need to pump the water elsewhere, I recommend use gravity drain to a separately procured water pump from another company. As I said, I'll let you know what happens. 22 February Update: E4 code and nothing pumping... I have contacted support for assistance today. I'll let you know what happens. Until this is resolved, I cannot recommend anyone buy this machine. 17 February 2024 Update: I got a hose I purchased from another company to fit the compression nut at the end of October. I've checked every day since then before I head for bed. Everything worked great until three days ago when I noticed a puddle of water in the room. Traced source and the device is leaking INSIDE the device and out the corner - just like all the other folks reported. I am so mad I cannot see straight. If I manually push the button to force it to drain through the powered hose it will -- however I have no plans to sit in that room for the next ten years and push that button every five minutes to get it to work, nor will I switch the drain to the unpowered method for gravity drain - that is NOT what I paid for. Once I calm down, I'll call them about sending their machine back and getting a refund. I'll let you know how their customer service work out. Until then, I cannot recommend anyone buy this machine. 21 October 2023 Update: The new compression nut shipped by ALORAIR arrived today. It was exactly the same as the first (supplied with dehumidifier) compression nut and fixed NOTHING. Same exact issue. I still have an expensive dehumidifier that I cannot hook up the supplied drain hose with to test... I will call them back tomorrow and ask to talk to an actual engineer. My guess is they will ship a new hose -- that also will not fix what looks more and more to be a SERIOUS QA problem. If ALORAIR cannot get its act together I may have to do a video with precise measurements (haven't used those gauges in years) that explains the physics of compression nuts and tolerances... Earlier (first) post: I paid extra for the version with the internal pump to push the dehumidified water someplace else. However, the supplied compression nut, when the supplied hose is inserted through the nut onto the dehumidifier's nipple - that the compression nut should screw onto, no longer reaches the screws. Either the nipple ring is mis-machined to be too large a circumference when the hose is attached to pass the nut, or the hose is too thick - causing the same issue, or a combination of both bad engineering on the nipple or the hose. I called tech support today and after the insulting, "no one else is having that issue" reply (I am a retired engineer - am guessing most buyers are simply switching to gravity option... I on the other hand want what I paid for); the tech person is sending me another compression nut - that unless the one I originally got on the dehumidifier was known not to work but shipped anyway - will likely not fix the issue. If you search enough for this issue, you will discover the issue is referenced in the manual for a different ALORAIR dehumidifier - the recommended solution there stated for the user to find a different (thinner walled?) hose on your own... IF the shipped compression nut fixes the issue, I will post that here and change the rating. BTW, if you view ratings in reverse chronological order (newest first), it seems to me that ALORAIR may have a serious QC issue in their product engineering?

96 day update was working fine yesterday today it no longer works. Will not turn on no error messages. I will be contacting customer service to see what my options might be, all the reviews speak highly of the customer service Mostly good so far but we will start with the bad. If your going to use the pump the compression fitting is difficult to impossible to install. Others have mentioned this issue and one person even posted a video advising people having trouble to use a wrench. I tried everything I could think of and the wrench but after almost an hour of trying and failing.( I don’t give up easily) even though it’s an hour of my life I won’t get back. I drove to the local big box hardware store and purchased a clamp. Problem solved in about 45 seconds upon my return home. The fitting is the reason this little can do machine received a 4 out of 5 rating from me. Let’s go with the good. The machine arrived well packaged and it definitely is well built and heavy duty. The packaging even included corner guards. Unboxing was easy controls are well marked and intuitive. Note the wider hose is for the gravity drain while the other is for the pump. If you can use gravity for your situation you will avoid the compression fitting. Unfortunately I need the pump. This afternoon I installed this in my crawlspace. Within two hours my humidity levels went from 68 percent to 55 percent. This even though I was unable to install the dehumidifier in the center of the space as I intended due to my existing site conditions in 70 year plus old home. I’m closer to my access hatch which I’m sure will make this machine run more. I’m also hopeful that the dehumidifier will help the entire space even though it’s not at the center. My space is 980 square feet. The unit is quiet with good airflow. The controls are good. The feet are easy to adjust, the cord is long and the pump works well so far. I started out running it on continuous operation for the first few days and will switch it to humidity level cycles. I will update this review in 30 days with my ownership experience. Thoughts that I think would make this unit better but did not weigh in to my star excluding the above mentioned compression fitting. Things to improve: 1. Do something with that darn compression fitting. Redesigning this with a clamp or if possible a quick connection would make your customers life’s better and guarantee 5 stars because the machine itself is rock solid out of the box. 2. Make this machine able to be wifi monitored and if possible controlled. This would really make this so much better. 30 day plus update: So far no issues with this dehumidifier. It has definitely done the job. My humidity levels have dropped to around 50 percent. Even with setting the humidity level it runs almost non stop. But I have not noticed a significant change in my electric bills. 69 day update: one thing I’ve done to improve controlling the unit and verifying humidity levels in my crawl space was to buy Govee temperature and humidity sensors and place them in the crawlspace. I can check the humidity of the crawlspace through my phone from anywhere In addition The other Govee product I added was a Govee outdoor plug. This plug has made my life easier as I no longer have to go in to my crawlspace to turn the unit off and on. As stated above even with the humidity range set the unit never seemed to shutdown. This Govee outdoor plug allows me to set a scheduled run time on off and control the unit from anywhere with my phone.
